Problem
I want to be alerted when PostgreSQL replication lag on a replica grows above some threshold value. The replica not being up to date with the primary is a significant issue – if the primary fails while there is significant lag, I cannot fail over to the replica without losing some data.
Description
It would be useful to have in Netdata a built-in alert configuration for when PostgreSQL replication lag passes some threshold value.
Looking at the existing alerts, there are already replication lag alerts for MySQL and Clickhouse.
I also noticed a replication lag alert was proposed here: #13664
Importance
nice to have
Value proposition
...
Proposed implementation
No response
